Grey water reclamation

Abstract

A grey water reclamation system for a recreational vehicle includes an on-board use that generates grey water having a contamination level, a grey water treatment tank fluidly connected to the on-board uses to collect the grey water and treat the grey water therein to form treated grey water, and a coagulant dispenser and a flocculant dispenser each fluidly connected to the grey water treatment tank and configured to supply a predetermined amount of coagulant and flocculant, respectively, to the grey water treatment tank. The system also includes a grey water supply tank fluidly connected to the grey water treatment tank configured to receive the treated grey water therefrom and supply the treated grey water to a particular on-board use. The predetermined amount of coagulant is based on the contamination level or a turbidity of the treated grey water.

         21 . A grey water reclamation system comprising:
 a source of grey water having a contamination level ;   a grey water treatment tank fluidly connected to the source to collect the grey water and treat the grey water therein and form treated grey water;   a coagulant dispenser fluidly connected to the grey water treatment tank and configured to supply a predetermined amount of coagulant to the grey water in the grey water treatment tank; and   a flocculant dispenser fluidly connected to the grey water treatment tank and configured to supply a predetermined amount of flocculant to the grey water in the grey water treatment tank,   wherein the predetermined amount of coagulant and/or the predetermined amount of flocculant is based on the contamination level or a turbidity of the grey water, and wherein the contamination level is based on an amount of surfactant in the grey water, the amount of surfactant being related to an amount of detergent or soap dispensed by the source.   
     
     
         22 . The grey water reclamation system of  claim 21 , wherein the predetermined amount of flocculant is based on the predetermined amount of coagulant. 
     
     
         23 . The grey water reclamation system of  claim 21 , wherein the grey water treatment tank includes a filtration system to separate contaminants from the grey water to form the treated grey water. 
     
     
         24 . The grey water reclamation system of  claim 21 , wherein the source a laundry appliance, a shower, or both. 
     
     
         25 . The grey water reclamation system of  claim 21 , further comprising a particular use to which the treated grey water is supplied, wherein the particular use is a toilet, a laundry appliance, a shower, or combinations thereof. 
     
     
         26 . The grey water reclamation system of  claim 21 , wherein the surfactant binds to the coagulant. 
     
     
         27 . A grey water reclamation system comprising:
 a source that generates grey water having a contamination level related to an amount of detergent or soap dispensed by the source;   a grey water treatment tank fluidly connected to the source to collect the grey water and treat the grey water;   a coagulant dispenser fluidly connected to the grey water treatment tank;   a flocculant dispenser fluidly connected to the grey water treatment tank; and   a controller configured to,
 based on the contamination level, a turbidity of the grey water as correlated to the amount of detergent or soap detected by a sensor, instruct the coagulant dispenser to supply a predetermined amount of coagulant to the grey water treatment tank, and 
 instruct the flocculant dispenser to supply a predetermined amount of flocculant to the grey water treatment tank. 
   
     
     
         28 . The grey water reclamation system of  claim 27 , further comprising sensors which detect surfactants and/or contaminants in the grey water, and provide data regarding contamination or turbidity to the controller for determining the contamination level. 
     
     
         29 . The grey water reclamation system of  claim 28 , wherein the controller compares a treated grey water turbidity to a desired or predetermined threshold of turbidity to determine the contamination level. 
     
     
         30 . The grey water reclamation system of  claim 27 , wherein the source is a laundry appliance, a shower, or both. 
     
     
         31 . The grey water reclamation system of  claim 27 , further comprising a particular use to which the treated grey water is supplied, wherein the particular use is a toilet, a laundry appliance, a shower, or combinations thereof. 
     
     
         32 . The grey water reclamation system of  claim 27 , wherein the controller receives the amount of detergent or soap and determines a typical detergent concentration for the grey water, the typical detergent concentration being correlated to a dosing starting point 
     
     
         33 . The grey water reclamation system of  claim 32 , wherein the dosing starting point is the predetermined amount of the coagulant and/or the predetermined amount of flocculant. 
     
     
         34 . The grey water reclamation system of  claim 32 , wherein the controller additionally doses beyond the dosing starting point based on the contamination level. 
     
     
         35 . A method for reclaiming grey water, the method comprising:
 determining a contamination level of grey water from a source by measuring the amount of detergent or soap dispensed by the source;   adding a coagulant to the grey water based on the contamination level to form coagulated particles in the grey water;   adding a flocculant to the grey water to aggregate the coagulated particles into flocs;   separating the flocs from the grey water to form treated grey water; and   providing the treated grey water to a laundry device, a toilet, a shower, a tub, or combinations thereof.   
     
     
         36 . The method of  claim 35 , wherein the determining includes measuring surfactants in the grey water. 
     
     
         37 . The method of  claim 36 , wherein the adding the coagulant binds surfactants to the coagulant to form the coagulated particles. 
     
     
         38 . The method of  claim 35 , wherein the source is the laundry device, the shower, or both. 
     
     
         39 . The method of  claim 35 , wherein the separating is via a mesh, sieve, gravity filtration, or a filter cartridge. 
     
     
         40 . The method of  claim 35 , wherein adding the flocculant includes adding a predetermined flocculant amount based on the coagulant.
